Syslogd is often used to turn machine messages or syslogs into events for further processing. Ultimately, alarms are generated which can trigger some type of notification.  The problem with the messages created by syslogd, is their nonstandard and loosely structured data format.  This post is about the end of Syslog and the evolution of IPFIX due largely to the fact that the data exported in IPFIX is highly structured.

Cisco 6509 NetFlow problems and recent improvements will be the main focus in this blog.  Since the reporting accuracy of your NetFlow or Flexible NetFlow Analyzer could also depend on the quality of the exported data, hopefully discussing some of the major NetFlow problems with 6500 series will help us better understand how exactly reporting on these switches works. I will also take this opportunity to highlight improvements made in the sup 2T. Read more »

OpenFlow and NetFlow are two completely different concepts. OpenFlow controls how packets are forwarded through network switches, and Netflow collects IP traffic information. It’s easy to think of the two as being related because both words contain the suffix “flow”.  This post should provide some clarity on the nature of each one of these two protocols. Read more »

Catalyst 6509 NetFlow support is essential, especially when the switch is set up as a core network device; this blog should help you get started with NetFlow traffic monitoring on 6500 series switches.

Enabling NetFlow on a 6509 is slightly different from the traditional IOS NetFlow setup. Here you need to keep in mind that NetFlow on the MSFC is collected in software, and on the PFC it is collected in hardware.  Beside the familiar IOS NetFlow commands,  Cisco 6509 NetFlow also requires enabling NDE in order to export flow statistics to the collector.

We figured out how to report on packet length with NetFlow.  All you have to do is enter “match ipv4 length total” in the flow record of the Flexible NetFlow Configuration .  This entry will export the element ipTotalLength   whereby the NetFlow and IPFIX reporting  tool can provide reports that look like this:

Read about virtual routing first before reading this post.  VRF aware Netflow is available in Scrutinizer since v7 and in IOS starting with 12.4(11)T, however I also saw in some documentation that support for VRF input was added in 15.0(1)M. This is of course via Flexible Netflow. You can set the input VRF as a key field in the NetFlow record, then use the VRF ID to filter reports based on that VRF in scrutinizer.
